Instructions
Preheat and Prepare
Preheat your oven to 375°F (190°C). If using a store-bought crust, place it in your pie dish and par-bake for 10 minutes. This step prevents a soggy bottom later.
Cook the Sausage
In a large skillet over medium heat, add olive oil. Once hot, crumble in the sausage and cook until browned, breaking it up with a wooden spoon. This step is especially great if you're using Italian sausage or experimenting with beef sausage recipes. Remove sausage and set aside, leaving some fat in the pan.
Sauté the Vegetables
In the same skillet, add chopped onions and cook until translucent, about 3 minutes. Add mushrooms and garlic, cooking until the mushrooms are browned and any moisture has evaporated — about 5–7 minutes. If adding spinach, stir it in during the last minute to wilt.
Whisk the Filling
In a large mixing bowl, whisk together the eggs, half-and-half, salt, pepper, and thyme or Italian seasoning until smooth and frothy.
Layer the Quiche
Evenly spread the sausage and mushroom mixture in the bottom of the pie crust. Sprinkle the shredded cheese over it. Then pour the egg mixture on top, letting it seep into all the nooks and crannies.
Bake
Bake in the preheated oven for 35–40 minutes, or until the center is just set and the top is lightly golden. A knife inserted in the center should come out clean.
Cool and Serve
Let the quiche cool for 10–15 minutes before slicing. This makes it easier to cut and enhances the flavors.
